Blizzard reveals that the upcoming add-on for their real-time strategy, StarCraft
2. According to the game's
official web site, StarCraft 2: Heart of the Swarm is going to be out on
March 12, 2013.

Here's a bit more about the story in Heart of the Swarm:

The Queen of Blades is gone. On the hellish planet Char, Jim Raynor harnessed
the power of an ancient Xel'Naga artifact in a desperate bid to stop the zerg
Swarm from overrunning the Koprulu sector, and the artifact restored Sarah
Kerrigan to her human form. Without their queen to guide and unify them, the
Swarm has fractured into several broods scattered throughout the Koprulu sector.
One of the greatest threats to the galaxy has been neutralized... or so it
seems.

Sarah Kerrigan is on the loose. Even without the terrible powers of the Queen
of Blades or the might of the Swarm at her command, the former Ghost remains
a foe not to be taken lightly. But if the artifact really did set her free,
then why is Kerrigan seeking out zerg broods scattered throughout the Koprulu
sector? What happened to Jim Raynor? Is she still pursuing her quest for vengeance,
or has her transformation given Kerrigan a new purpose?

Of course they are. Working for blizzard is like working at a luxury spa. You can waste money and take your sweet time relaxing.

Don't worry about the deadline now the fans will love every game we develop. If they don't make the release we can just scrap the code and rewrite it again and say it's because were still trying to balance the game.

Don't think I'm going to spend $60on this one. SC2 single player gameplay was kind of boring for me (except for the story and cutscenes)... and I suck massively at multiplayer so that wasn't worth the effort.

Now if it was $10-15 DLC I would consider it. But if that was the case it would have released already
